The first stream that passes through liveadder plays but the second does not, even if I pause the first and only play the second. 2 channel, 44.1 KHz audio, 16 bits, default latency.<br>

</div>The use-case that liveadder was designed for is RTP streams where you<br>
have multiple discontinuous streams arriving in real-time. So if you<br>
have two pads, you want to output a buffer if you have one one either<br>
pad (because you're not guaranteed to have one on both), but you also<br>
want to make sure to properly mix if you have data on both.<br>

</div>It should mix them. If they are identical, that will probably result in<br>
doubling the volume. It's called adder because the mixing algorithm is<br>
to add the samples together.<br>
<div class="im"><br>

<br>
</div>Yes, unlike adder, liveadder takes great pain to make sure incoming<br>
streams are synchronized before they are mixed.<br>
